The apostle charged the Ephesians in the name and by the authority of the Lord Jesus, that having professed the gospel, they should not be as the unconverted Gentiles, who walked in vain fancies and carnal affections. Do not men, on every side, walk in the vanity of their minds? Must not we then urge the distinction between real and nominal Christians? They were void of all saving knowledge; they sat in darkness, and loved it rather than light. They had a dislike and hatred to a life of holiness, which is not only the way of life God requires and approves, and by which we live to him, but which has some likeness to God himself in his purity, righteousness, truth, and goodness. The truth of Christ appears in its beauty and power, when it appears as in Jesus. The corrupt nature is called a man; like the human body, it is of divers parts, supporting and strengthening one another. Sinful desires are deceitful lusts; they promise men happiness, but render them more miserable; and bring them to destruction, if not subdued and mortified. These therefore must be put off, as an old garment, a filthy garment; they must be subdued and mortified. But it is not enough to shake off corrupt principles; we must have gracious ones. By the new man, is meant the new nature, the new creature, directed by a new principle, even regenerating grace, enabling a man to lead a new life of righteousness and holiness. This is created, or brought forth by God's almighty power.
12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
English Standard Version
12 For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
12 God means what he says. What he says goes. His powerful Word is sharp as a surgeon's scalpel, cutting through everything, whether doubt or defense, laying us open to listen and obey.
New King James Version
12 For the word of God is living and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.
New Living Translation
12 For the word of God is alive and powerful. It is sharper than the sharpest two-edged sword, cutting between soul and spirit, between joint and marrow. It exposes our innermost thoughts and desires.
Observe the end proposed: rest spiritual and eternal; the rest of grace here, and glory hereafter; in Christ on earth, with Christ in heaven. After due and diligent labour, sweet and satisfying rest shall follow; and labour now, will make that rest more pleasant when it comes. Let us labour, and quicken each other to be diligent in duty. The Holy Scriptures are the word of God. When God sets it home by his Spirit, it convinces powerfully, converts powerfully, and comforts powerfully. It makes a soul that has long been proud, to be humble; and a perverse spirit, to be meek and obedient. Sinful habits, that are become as it were natural to the soul, and rooted deeply in it, are separated and cut off by this sword. It will discover to men their thoughts and purposes, the vileness of many, the bad principles they are moved by, the sinful ends they act to. The word will show the sinner all that is in his heart. Let us hold fast the doctrines of Christian faith in our heads, its enlivening principles in our hearts, the open profession of it in our lips, and be subject to it in our lives. Christ executed one part of his priesthood on earth, in dying for us; the other he executes in heaven, pleading the cause, and presenting the offerings of his people. In the sight of Infinite Wisdom, it was needful that the Saviour of men should be one who has the fellow-feeling which no being but a fellow-creature could possibly have; and therefore it was necessary he should actual experience of all the effects of sin that could be separated from its actual guilt. God sent his own Son in the likeness of sinful flesh, Romans 8:3; but the more holy and pure he was, the more he must have been unwilling in his nature to sin, and must have had deeper impression of its evil; consequently the more must he be concerned to deliver his people from its guilt and power. We should encourage ourselves by the excellence of our High Priest, to come boldly to the throne of grace. Mercy and grace are the things we want; mercy to pardon all our sins, and grace to purify our souls. Besides our daily dependence upon God for present supplies, there are seasons for which we should provide in our prayers; times of temptation, either by adversity or prosperity, and especially our dying time. We are to come with reverence and godly fear, yet not as if dragged to the seat of justice, but as kindly invited to the mercy-seat, where grace reigns. We have boldness to enter into the holiest only by the blood of Jesus; he is our Advocate, and has purchased all our souls want or can desire.
